Thanks, that helps narrow it down! I used: Microsoft EdgeVersion 121.0.2277.128 (Official build) (64-bit) No plugins/addons. I was unable to reproduce the crash. I tried going in and out of the bedroom multiple times and at different points of the story. The code to go from the bedroom to the TV room is the same for all of the doors in the game, so if it crashes on one it could theoretically crash on any of the doors. The only thing I can think of that would have caused a crash is a problem loading the sound or the next room. When I was first programming the doors, there were no sounds available and I prevented crashing with an if statement that says if the sound is null, skip it, so my thought is that it had the sound file listed but couldn't actually load it for some reason. If we revisit the game for more chapters, I'll do some more digging and see if I can get it to crash.
